Abstract The efficacy of 14 insecticides for control of velvetbean caterpillars and stink bugs was evaluated at the University of Georgia Coastal Plain Experiment Station, Tifton, GA. The insecticides were foliar-applied on 31 Aug on ‘Cook’ soybeans planted on 17 May. Individual plots were 4 rows wide × 50 ft long with alleys 6 ft wide on each end and 2 border rows on each side, arranged in a RCBD with 4 replications. Each spray concentrate was applied with a CO2-powered backpack sprayer with 4, TX-12 nozzles on a 6 ft boom (2 nozzles per row) at 40 psi that delivered 17.6 gal/acre. Each plot was sampled prior to treatment and on 2, 7, 14 and 21 DAT, by taking a 20-sweep sample (15-inch diam net) from a single row. Soybeans were in the R5 growth stage (pods rilling with seeds) during the testing period. At 28 DAT, the percent defoliation was visually estimated for all plots. The data were subjected to ANOVA and Duncan’s multiple range test.

Bermudagrass (Cynodon spp.) is the foundation of the turfgrass industry in most tropical and warm-temperate regions. Development of bermudagrass as a turfgrass began in the early 1900s. Many of the cultivars commercially available today have been cooperatively released by the U.S. Department of Agriculture Agricultural Research Service (USDA-ARS) and the University of Georgia at the Coastal Plain Experiment Station in Tifton, GA.

Released in 2004 by the University of Georgia and U.S. Dept. of Agriculture, `Vernon' is an early season rabbiteye blueberry (Vaccinium ashei Reade), having large fruit size, good yields and excellent plant vigor. `Vernon', tested as T-584, was selected in 1990 at the Coastal Plain Experiment Station in Tifton, Ga. from a cross of T-23 × T-260. `Vernon' fruit ripens early with the cultivar Climax in south Georgia, and few days before `Premier'; however, `Vernon' flowers 5 to 10 days after the standard cultivars. On average over a 6 year period, `Vernon' yielded 5.8 kg/plant per season, compared to 3.1 and 4.5 kg/plant for `Climax' and `Premier', respectively. Berry stem scar, color, firmness, and flavor of the new cultivar are good to excellent. Berry size of `Vernon' is considerably large, averaging 2.05 g/berry over 4 locations in 2003, compared to only an average weight of 1.56 g/berry for `Climax'. `Vernon' berries are firmer than `Premier'. Propagation of the new cultivar is easily accomplished from softwood cuttings. Chill hour requirement is estimated to be in the range of 500 to 550 hours (<7 °C). `Vernon' should be planted with other rabbiteye blueberry cultivars with a similar time of bloom to provide optimum pollination. Propagation rights are controlled by Georgia Seed Development Commission, 2420 S. Milledge Avenue, Athens, GA 30606 (for more information go to www.gsdc.com).

Careful Management

Even with careful management, within-field practices are often insufficient to prevent considerable nonpoint source pollution to adjacent streams. Water resources suffer from sediment, N, and P transported in surface runoff and N in subsurface movement when fields are cultivated up to stream banks. The maintainance of forested buffer systems between farmland and streams has been proposed as a remedy for mitigating pollution. Chemical movement through such a buffer system has been monitored for several years at the University of Georgia Coastal Plain Experiment Station. With the aid of that data, the Riparian Ecosystem Management Model is being developed to simulate biological, chemical, and hydrologic processes in order to evaluate the effectiveness of buffer system management for reducing the influx of pollutants to streams. The model allows an examination of the long-term potential of a buffer system under changing environmental conditions.

Abstract Flue-cured tobacco was transplanted on 29 Mar at the Coastal Plain Experiment Station in Tifton, GA. Production practices were used according to Georgia Cooperative Extension Service guidelines. A preplant incorporated tank mix of the following was applied: Tillam and Devrinol for weed control, Ridomil for blue mold control, Nemacur for nematode suppression, and Lorsban for wireworm and mole cricket control. Fertilizer (6-6-18) was applied in a split application at a rate of 1000 lb/acre. Plots 4 rows wide (44 inch row spacing) × 20 ft long were arranged in a RCBD with 4 replications. On 9 Jul all plants in each plot were cut down to a 12 inch mainstalk and all leaves were removed. All cut plants were then allowed to regrow with 2-3 main shoots. On 23 Jul, 5 insecticide treatments (plus an untreated control) were applied to the center 2 rows of selected plots using a CO2-powered backpack sprayer equipped with three TX-12 nozzles directed over a single row, delivering 30.3 gpa at 40 psi. The number of live hornworms was recorded per 10 plants on row 2 of each plot prior to the application, and 5, 10, and 14 DAT. All data were subjected to ANOVA and Duncan’s Multiple Range Test.

Field screening for potato leafhopper, Empoasca fabae Harris, resistance among peanut, Arachis hypogaea L., genotypes were conducted for three consecutive years (2001, 2002, and 2003) at the University of Georgia, Coastal Plain Experiment Station in Tifton, GA. Irrigated field trials were used for evaluations, and plants were grown without any pesticides other than preplant and occasional postemergence herbicides. Results from these replicated tests showed a wide-range of leafhopper damage. During each of the 3 yrs, ‘Georgia-01R’ consistently had the lowest leafhopper damage rating of all genotypes tested. Likewise, each year ‘Georgia Hi-O/L’ had the highest leafhopper damage rating. ‘Georgia Green’ and other cultivars and breeding lines were intermediate between Georgia-01R and Georgia Hi-O/L for leafhopper ratings. These field trials confirmed the multiple-pest resistant runner-type cultivar Georgia-01R as a new source of leafhopper resistance in peanut.

A new southern highbush blueberry cultivar named `Camellia' was released in 2005 by The University of Georgia and the USDA–ARS. `Camellia' is a hybrid containing mostly Vaccinium corymbosum and a small amount of V. darrowi. The new cultivar was selected in 1996 at the Coastal Plain Experiment Station in Tifton, Ga. from a cross of MS-122 × MS-6, and was tested as TH-621 in plantings at Alapaha, Ga. beginning in 1998. `Camellia' has an estimated chill requirement of 450 to 500 hours (<7 °C). It is an early- to mid-season cultivar, having berries that are large, with a very light blue color, and a small, dry picking scar. Berry firmness is good and flavor is very good. `Camellia' flowers 5 to 8 days after `Star' and `O'Neal' in south Georgia, and ripens 4 to 9 days after `Star', and with `O'Neal'. Plants are highly vigorous, with strong cane growth and an open, upright bush habit and a narrow crown. Yields have been similar to `Star' and greater than `O'Neal'. `Camellia' should be planted with other southern highbush blueberry cultivars with a similar time of bloom for cross-pollination (`Star' and `O'Neal' suggested). It is recommended on a trial basis at this time. `Camellia' requires a license to propagate.
